Winterizing Your Home to Prevent Appliance Leaks
Last updated October 25, 2026
The short answer
Why Winter Causes Appliance Leaks
Cold weather can freeze water inside supply lines, especially those in unheated areas like garages, crawl spaces, and exterior walls. When water freezes, it expands and can crack pipes or fittings. Even a tiny crack may not leak until the ice thaws, so the damage can go unnoticed for days.
Temperature swings also affect appliances. A refrigerator's water line can develop stress fractures from repeated freezing and thawing. Washing machine hoses can become brittle in the cold. The result is a slow drip or a sudden burst that soaks floors, walls, and belongings.
Steps to Protect Pipes and Lines
Start by locating all water supply lines that run through unheated spaces. Insulate them with foam pipe covers or heat tape. For outdoor faucets, disconnect hoses and drain the lines. If you have a sprinkler system, blow out the water or have a professional do it.
Inside your home, keep the thermostat set to at least 55 degrees Fahrenheit, even when you are away. Open cabinet doors under sinks to allow warm air to circulate. Seal any gaps around pipes that enter your home to block cold drafts. These simple steps reduce the risk of frozen lines.
- Insulate pipes in the garage, attic, and crawl spaces
- Disconnect and drain outdoor hoses and faucets
- Keep garage doors closed to retain heat
- Let faucets drip slightly during extreme cold
- Check for drafts around pipe entry points
Check Appliances Before Cold Weather
Inspect your refrigerator's water line for kinks, cracks, or loose connections. Move the fridge away from the wall to see the line and the shutoff valve. Replace any suspect line with a braided steel hose, which is more durable. Also, check the ice maker connection for drips.
For washing machines, examine the fill hoses for bulges or wear. Replace rubber hoses with stainless steel ones if they are old. After each use, turn off the water supply to the washer if you can. This prevents pressure buildup that can cause the hoses to burst.
What to Do If You Find a Leak
If you discover a leak, shut off the main water valve immediately. This stops further water flow and limits damage. Then, turn off the power to the affected appliance if it is safe to do so. Do not touch electrical switches if water is near them.
Dry the area as quickly as you can to prevent mold growth. Use towels, mops, and fans to remove standing water. For large leaks, you may need to remove baseboards and drywall to dry out the framing. If the leak is significant, contact local water damage pros to assess the situation.
If you live in a cold climate, keep your shutoff valve location written down so you can act fast in an emergency. Acting quickly can mean the difference between a simple cleanup and major repairs.
- Shut off the main water valve right away
- Turn off power to the appliance if safe
- Remove wet items to a dry area
- Use fans and dehumidifiers to dry the space
- Watch for signs of mold in the following days
Long-Term Winterizing Habits
Winterizing is not a one-time task. Each fall, review your pipes, hoses, and appliance connections. Replace any parts that show wear. Keep your home's temperature stable, even during vacations. A small investment in insulation and replacement hoses can prevent a major mess.
Consider installing a smart water leak detector near appliances. These devices alert you to moisture early, so you can act before water spreads. Some models shut off the water automatically. While no system is foolproof, they add a layer of protection during the coldest months.
Water damage does not wait
Every hour counts once water gets into floors and walls. One call starts the response.

What temperature should I set my thermostat to prevent frozen pipes?
Set your thermostat to at least 55 degrees Fahrenheit, even when you are away. This keeps indoor pipes above freezing. If you have pipes in exterior walls, open cabinet doors to let warm air reach them.
Should I disconnect my garden hose in winter?
Yes, disconnect and drain garden hoses. If you leave a hose attached, water can freeze in the spigot and crack the pipe. Store hoses indoors or in a shed to extend their life.
How do I know if my washing machine hoses need replacing?
Check for cracks, bulges, or leaks at the connections. If the hoses are more than five years old, replace them with stainless steel braided hoses. Look for any signs of wear before cold weather hits.
